Consider the function $ f(x)=x^{2}-4 x+8 $ on the interval $ [0,4] $. Verify that this function satisfies the three hypotheses of Rolle's Theorem on the inverval. \[ \begin{array}{l} f(x) \text { is continuous } \rightarrow \text { on }[0,4] \sim \text {; } \\ f(x) \text { is differentiable } \sim \text { on }(0,4) ~ ; ~ a n d ~ \\ f(0)=f(4)= \end{array} \] Then by Rolle's theorem, there exists at least one value $ c $ such that $ f^{\prime}(c)=0 $. Find all such $ c $-values. If there is more than one value, enter them in a comma-separated list. (Round your answer to within three decimal places if necessary.) \[ c= \]

Consider the six station process shown below. The probability of a part being defective at station 1 is P1, at station 3 is P3, and similarly up to station 6. Defects from station 1 are scrapped with probability 1-Q1 and reworked at station 1 with probability Q1. Defects from station 4 are scrapped with probability 1-Q4 and reworked at station 4 with probability Q4. Defects from station 5 are scrapped with probability 1-Q5 and reworked at station 2 with probability Q5. Incoming parts, I, are split into three groups. The A1 fraction of all incoming parts go to station 1, A2 of all incoming parts go to station 2, and the remaining portion, A3, go to station 3. Let I denote the input into the system and let O denote the sum of the output of good parts from stations 4, 5, and 6. Represent the total steady state output of the process as a function of I, P1, P3, P4, P5, P6, Q1, Q4, Q5, A1, A2, and A3. Assume the following values for the parameters. P1 = 0.1, P3 = 0.2, P4 = 0.3, P5 = 0.15, P6 = 0.25, Q1 = 0.5, Q4 = 0.25, Q5 = 0.25, A1 = .22, A2 = .34, and A3 = .44. If the input is 250, what is the value for the output?

Consider a torsional system consisting of two discs mounted on a shaft, as shown in Figure Q4. The three segments of the shaft have rotational spring constants $k_{t1}$, $k_{t2}$ and $k_{t3}$ as indicated in the figure. Also shown are the two discs with the mass moments of inertia $J_1$ and $J_2$ as well as the rotational degrees of freedom $\theta_1$ and $\theta_2$. Given that $k_{t1}$ = 3X Nm/rad; $k_{t2}$ = 3Y Nm/rad; $k_{t3}$ = 3Z Nm/rad; $J_1$ = 3Y kgm² and $J_2$ = 1Z kgm². Initial conditions at t = 0 sec are $\theta_1$(0) = 0, $\theta_2$(0) = 0.05 rad and all initial rotational velocities for both disks are zero. a. Write out the equations of motions in matrix form (CO3: PO2-5 marks) b. Calculate the natural frequencies and mode shapes of the torsional system (CO3: PO2-10 marks) c. Compute the free vibration responses of both disks (CO3: PO2-10 marks)
